 A joint reliability–redundancy optimization approach for multi-state series–parallel systemsZhigang Tian, Gregory Levitin and Ming J. Zuo Reliability Engineering and System Safety, 2009, vol. 94, issue 10, 1568-1576 Abstract: In this paper, we present a practical approach for the joint reliability–redundancy optimization of multi-state series–parallel systems. In addition to determining the optimal redundancy level for each parallel subsystem, this approach also aims at finding the optimal values for the variables that affect the component state distributions in each subsystem. The key point is that technical and organizational actions can affect the state transition rates of a multi-state component, and thus affect the state distribution of the component and the availability of the system. Taking this into consideration, we present an approach for determining the optimal versions and numbers of components and the optimal set of technical and organizational actions for each subsystem of a multi-state series–parallel system, so as to minimize the system cost while satisfying the system availability constraint. The approach might be considered to be the multi-state version of the joint system reliability–redundancy optimization methods.
